Portable air tank booster

ABSTRACT

A portable air tank  30  that adapts from a ⅜ inch air supply line  17  to a 1 inch delivery line  15  and  18  and powers a one inch heavy duty extended anvil impact wrench  23  with a continuous supply of air power 110 to 120 psi. The air wind throw is reduced from 150 feet to 15 feet 18. The tank is portable and easily adapted to various air compressors.

BACKGROUND FIELD OF INVENTION

[0002] This invention relates to air compression that powers the 1″heavy-duty extended anvil impact wrench, specifically to adapting aportable air tank that boost the pressure per square inch (PSI).

DESCRIPTION OF PRIOR ART

[0003] Manufacturing and repair shops use 1″ heavy-duty impact wrenchesfor removing wheels and other jobs. These wrenches are powered by largeair compressors that have long hoses leading to various work stationsthroughout the shop.

[0004] Originally these one inch air hoses had to be dragged around totake off wheels from trailers and trucks. The length of the hose maybe150 feet or more.

[0005] Thus due to the length of the hose, the psi would soon drop from120 to about 90 psi. This caused the workers to wait for the compressorto build back up again. Dragging this long hose and waiting for pressurebuild-up made working conditions tiresome and time consuming for theshopworkers.

SUMMARY

[0006] In accordance with the present invention, a portable air tankbooster comprises a 6.5 gallon air tank with a ⅜″ rubber air hoseconnector on one end and one inch adapter on the other end whichattaches 15 feet of one inch air hose to the tank and leads to an anvilimpact wrench.

OBJECTS AND ADVANTAGES

[0007] Accordingly, several objects and advantages of the presentinvention are;

[0008] (a) to provide a continuous supply of air power;

[0009] (b) to provide easy hook-up to air couplers in the air supplysystem;

[0010] (c) to provide easy monitoring of air pressure;

[0011] (d) to provide emergency road use to large trucks by adapting totheir air tank reservoir;

[0012] (e) to provide easy storage of air hoses;

[0013] (f) to provide a stronger air pressure for 1″ impact wrench;

[0014] (g) to provide less weight and easier portability for impactwrench operation;

[0015] (h) to provide reduced length of air wind throw from 150 feet to15 feet;

[0016] (i) to provide a “buildup” of air pressure near the heavy dutyextended anvil impact wrench; and

[0017] (j) to provide a smaller and cheaper air compressor that gives alarger volume of air to power the heavy duty one inch extended anvilimpact wrench.

[0018] Further objects and advantages are to provide a ⅜″ air hose and asmaller, less expensive compressor that delivers a shorter air windthrow, and adjusts from a ⅜″ air hose to 1″ air hose which delivers acontinuous wind throw of 110 to 120 psi power to the 1″ extended anvilimpact wrench by allowing air pressure “build-up” near the impact wrenchoperation. Still further objects and advantages will become apparentfrom a consideration of the ensuing description and drawings.

DESCRIPTION—FIGS. 1A to 1C—Preferred Embodiment

[0032] A preferred embodiment of the present invention is illustrated inFIG. 1B ; FIG. 5A; FIG. 6A to 6D; and FIG. 7. The portable air tankbooster is 12.5 inches in diameter and 38.5 inches long (FIG. 1B andFIG. 2). The tank is made of heavy metal that can be cut and welded. Thetop handle 14 (FIG. 4) and the side hooks 13 (FIG. 3) are made of ⅜ inchdiameter pipe. These are bent to shape and welded into place. Thehandles/hooks on the ends of the tank serve as a rap around for the 15feet, one inch air hose connected to the booster tank.

[0033] The tank rests on feet 12 (FIG. 2) made from {fraction (1/16)}inch thick by 2½ inches wide and 20 inches long. These feet are weldedin place. Air pressure in the tank is monitored by a pressure gauge 16(FIG. 5B). This gauge is screwed into the tank.

[0034] The tank receives its air supply through a ⅜ inch male coupling17 (FIG. 5A) threaded into the top of the booster tank 30. The deliveryend of the tank 30 is a female coupling threaded into the tank one inchin diameter 15 (FIG. 6A). Fifteen feet of rubber air hose one inch indiameter 18 (FIG. 6B) is attached to the booster tank. A ¾ inch adapteris located on the end of the one inch, fifteen foot cord 19 (FIG. 6C) toallow for a ¾ inch plug 20 (FIG. 6D) that attaches a one inch heavy dutyextended anvil impact wrench 23 (FIG. 7).

[0035] FIGS. 10-11: Additional Embodiments

[0036] Additional embodiments are shown in FIGS. 10 and 11; in each casethe invention is shown powered by a smaller compressor and supply line32,31 (FIG. 10 is an electric compressor and FIG. 11 is a gasolinecompressor).

[0037] FIGS. 8A-8E and FIG. 9—Alternative Embodiments

[0038] There are various possibilities with regard to the portablebooster. FIG. 9 shows a truck reservoir powering the portable air tankbooster tank 25 (FIG. 9).

[0039] Large trucks air brake reservoir tank 25 (FIG. 8B) has a lineleading to the air brakes 27 (FIG. 8C). Install a ½ inch “t” 26 (FIG.8C) and divert the air to the air booster tank through a ⅜ inch adapter29 (FIG. 8E).

[0040] Advantages

[0041] From the description above, a number of advantages of my portableair tank booster become evident:

[0042] (a) The air impact worker does not have to drag around a long,heavy 1-inch air hose to each truck to take wheels off.

[0043] (b) The psi does not drop due to a shorter air wind throw.

[0044] (c) The booster tank provides a continuous supply of air power at120 psi.

[0045] (d) The specially designed handle allows the tank to be easilytransported.

[0046] (e) Truck drivers can adapt a coupler to their trucks air tankreservoir to run a line to the booster tank for emergency road use.

[0047] Operation—FIGS. 7 and 8A-8E

[0048] The manner of using the portable air tank booster is bestdescribed in FIGS. 7 and 8A-8E. In large truck repair shops, there aremany ⅜ inch steel pipe air roots to power impact wrenches. This ⅜ inchair root attaches to a specially designed air tank of heavy metal about6.5 gallon capacity 30 (FIG. 7).

[0049] The tank air gauge 16 (FIG. 7 ) monitors air pressure from 0-160.A one inch air hose is attached to the side of the air booster tank andplugs into the one inch extended anvil impact wrench 23 (FIG. 7) todeliver 120 psi. The air wind throw is reduced from 150 feet to 15 feet,thus giving a steady and greater force due to the build-up of airpressure in the portable air tank boosters.

[0050] Conclusion, Ramifications, and Scope

[0051] Accordingly, the reader will see that the portable air tankbooster can be used to reduce work time, and save expense for toolmakers, shop workers/owners, and truck drivers. Furthermore, theportable air booster tank has the additional advantages in that

[0052] it permits shop owners to accommodate a one inch air hose using asmaller compressor and supply line;

[0053] hook handles allow the 15 feet air hose to be wrapped around theportable tank for easy transporting;

[0054] it has a handle on top for easy transporting;

[0055] it delivers a greater psi (120 vs 90 psi);

[0056] it speeds up work time;

[0057] it reduces weight for the impact wrench operator to drag behindthe wrench;

[0058] it reduces shutdown time for truck drivers that breakdown on theroad.

[0059] Although the description above contains many specificities, theseshould not be construed as limiting the scope of the invention but asmerely providing illustrations of some of the presently preferredembodiments of this invention. For example, the portable air tankbooster can have other sizes and shapes; other colors; other adapters topower larger impact wrenches; home, shop, or truck use, etc.

[0060] Thus the scope of the invention should be determined by theappended claim and its legal equivalents, rather than by the examplesgiven.

I claim:
 1. A booster air reservoir tank comprising: a. a tank ofsufficient size to accommodate a substantial air pressure, b. said tankhaving a plurality of adaptors, and c. means for joining said tank atsaid adaptors providing access to air pressure reservoir, whereby an airimpact wrench power can be continuously maximized.
